When you have Seed inboxes, it may take a while to complete the login as inboxes are evaluated as part of the login. It is better to handle inbox evaluation as a separate activity soon after the login but with a dynamic count showing the inbox evaluation( eg app icon with an animated batch count). So the user will know if the count is fully loaded or not, but the advantage is. the page gets loaded fast without having to wait for the inboxes to load. If the user is going to use some other app he can straightaway move to that app without having to wait for the inbox to complete.
